Okay, let's analyze this post:
The 'healbot' does generate enmity, but not for the player itself. Granted this never really becomes an issue in normal circumstances, but I have seen some scholars pop up their fairy skill at the worst possible moments (mostly on add-spawns with blank aggro sheets) which has gotten their fairy KO'd. It escapes me why would you bring up the other point, as scholars are supposed to excel at single-target healing. It's not like the WHM can't do some nasty single-target healing with some decent sustainability, ie. a divine sealed regen (which can be applied directly after the DS cast and refreshed at 1s of DS left for 34s~ of DS-potency regen per minute), on top of just curing with DS or otherwise and getting those procs in. Sure, the SCH has cheaper and better single-target heals over time, but then what?
Needing to do something and it being advisable to do something are different things. If you want to snipe the fairy buffs and skills in terms of eyeing the 15y range optimally for as many people as possible (or 30 for Selene, which is a non-issue), you should place it. If you want to minmax Embrace up-times in dodge-heavy content so that you can manually embrace while you yourself move - you should have the fairy placed and re-placed on demand. If you want your Eos buffs to reach the tank in the Twister-phase of T5, you will want to place her to a spot where she doesn't get plummeted but her own skills reach the tank (and the melee who can get occasionally get plummeted when applying hits from a certain angle on Twin at certain times), also possibly re-placing her on demand or have her next to you and then temporarily placed for the skills themselves, followed by another Heel command. I could go on, but the point should be apparent by now.
Yes, but how is this relevant to the scholar being 'easier'?
It would make sense that the easier content is easier to do, yes. That aside, being able to have the fairy on Sic doesn't mean you should ever have it on Sic. Unless, of course, you want to lose your on-demand "enhanced cure II" which you mentioned, seeing as the fairy's AI is slow on the uptake and most of the time you would want to spam her to do embrace ahead of the tank dropping sub-80%, like you would cure on WHM just before a hit is about to land and thus keep up with the damage easier. Any decent scholar will not autopilot easier content either, because manual embracing will always maximize their DPS-times.
How easy something is sub-50 is meaningless. The game starts at 50. Agreed, though, it's pretty funny to see those scholars afk when I level my alts.
This is true but doesn't really help with your argument of the scholar being easier to play. As opposed to just sitting there waiting for damage to happen on a WHM, you could play actively and fast-pacedly on the scholar. But yeah, it's not like you can't also throw in some aeros or stones on the WHM if going OOM is not an imminent threat.
Aetherflow is 20%.
Yes, Lustrate is godly. I do agree it didn't need a buffage from 20% to 25% in 2.1. And I would also agree that Lustrate is superior to Benediction (dat animation delay), but it doesn't mean the latter can't be used well, either. Lustrate is a ridiculously good skill, but it is just there to solidify the SCH as the superior single-target healer which is what it is supposed to be anyway.
The rest of the post I can't bother to quote separately but you are basically bringing up every good side of the SCH vs. what you feel to be the drawbacks of the WHM, as well as using the fact it takes very little effort to be a scrub-level scholar as a premise to your argument of the scholar being easier to play. Well, it sure as hell doesn't take a lot to be a lazy, mediocre scholar. But this is not what we aim to be when we minmax and micro at max efficiency levels, minding everything what goes on in the battle field. When you take into account what it takes at the mentioned levels of play, the situation will change.
And yes, I have both classes, having done all content on both. For what it is worth, I think both classes require effort to master, whereas it is easier to slip unnoticed as a bad/mediocre SCH compared to an aggro-pulling or OOMing WHM. On the other hand, at max levels of play, I feel like the SCH is a tad more challenging.
